The sisters of a former priest who was convicted of their rape and jailed for eight years have called for the Director of Public Prosecutions to appeal the sentence.
Earlier this month, Richard Brennan, aged 64, who is originally from Rathfarnham but had been working in the United States, pleaded guilty during his trial to raping and indecently assaulting his sister Paula Fay when she was between 15 and 17 years old.
He also pleaded guilty to raping and indecently assaulting Catherine Wrightstone when she was between nine and 13 years old and he admitted indecently assaulting a third sister, Yvonne Crist, when she was 20 and he was 18.

He changed his plea to guilty after all three of the sisters had given evidence at the Central Criminal Court and two of them had been cross-examined.
The judge imposed a global sentence of nine years and suspended the final year.
An older brother, 67-year-old Bernard Brennan, was jailed last month for four and a half years for the sexual abuse of Ms Crist and Ms Fay.
Speaking on RTÉ's Oliver Callan programme, Ms Fay and Ms Wrightstone also called for reforms to how cases of historical sexual abuse are handled and for witnesses to get paid time off work to attend court, similar to jurors.
"I think Irish courts seem to have broad discretion over such cases as ours, and lenient sentences, especially in historical sexual abuse cases, are sometimes justified on the basis of remorse, time elapsed and, one of the things I find a little bit disturbing, is the offenders recent good character as stated in character references provided by family and friends who only know what that person allows them to know," Ms Wrightstone said.

She added: "So, in terms of reform, I would love to see the introduction of mandatory, binding, sentencing guidelines that treat sexual abuse and rape as serious offences regardless of the time elapsed.
"And create a statutory offence under sexual assault for sibling sexual abuse."
Ms Wrightstone also called for mitigation based solely on family support and a lack of other convictions to be disallowed.
"These predatory urges don’t just magically disappear, especially when there is no intervention and when decades of denial of abuse by the perpetrator are present, which was the case with Richard. It was denial right up until the very end," she said.
"I would also love to see them issue judicial training directives and case law clarification, via statute, that family support must not be considered a mitigating factor unless requested by the survivor," she added.
Ms Wrightstone said any updated legislation must clarify that delayed disclosure of offences due to trauma and family pressure do not lead to more lenient sentencing.

"The seriousness of the offences does not diminish over time. The law should reflect the continuing harm."
She said it was also important for the voices of survivors to be included when "shaping policy", along with mandatory consecutive sentences for multiple victims and mandatory training for judges regarding sibling sexual abuse cases.
Ms Fay said it was vital for witnesses to be entitled to paid time off work for the duration of a trial they are involved in, particularly in a trial of this nature.
"When I sought leave from my job, I was informed all I was entitled to was to either take annual leave or unpaid leave. That there was nothing in law to protect me as a witness," she said.
Witnesses are entitled to paid leave for the day they are testifying but not for the whole trial.
"I was completely committed to this process from the very beginning, and I feel that we need to be treated differently," Ms Fay said.
She added: "I know that jury members are entitled to be paid through their employment when they’re on a jury, for the entire trial, and I feel that something needs to change that a witness is also doing their civic duty. I feel it is exactly the same."
